That's one of my favorites. I use a lot of Tetras, but only in taller,
covered containers. AFAIK, they (and their imitator) are the only kind that
needs to or should reach the surface. They *are* a bit noisy, too.
Some sponge filters have a larger diameter lift tube, and use an airstone
which makes them pretty quiet. Others, like the Dirt Magnets split the
airstream into four smaller sets of bubbles for the same effect.
I use the Dirt Magnet Jrs, and the Lee equivalents, cut down low enough to
work nicely in plastic shoeboxes or sweater boxes.
The box filters all have the ability to trap eggs or babies, so I avoid
them. The floss is a less effective nitrogen bacterial conversion bed than
foam, IMHO. I also use a lot of under-gravel filtration.
